Homework 8 Due at the beginning of class March 26
... Due at the beginning of class March 26 1. You will model the ocean as a conductor to determine if you can find the Titanic using a ‘probe’ consisting of a conductor suspended below a moving ship and held at a potential of 100 V. Assume that no current can flow anywhere but to the ocean bottom made o ...

... • There are two magnetic fields, H and B. In a vacuum they are indistinguishable, differing only by a multiplicative constant that depends on the physical units. Inside a material they are different. The term magnetic field is historically reserved for H while using other terms for B. Informally, th ...

Scanning SQUID microscope
A Scanning SQUID Microscope is a sensitive near-field imaging system for the measurement of weak magnetic fields by moving a Superconducting Quantum Interference Device (SQUID) across an area. The microscope can map out buried current-carrying wires by measuring the magnetic fields produced by the currents, or can be used to image fields produced by magnetic materials. By mapping out the current in an integrated circuit or a package, short circuits can be localized and chip designs can be verified to see that current is flowing where expected.
